LOCOMOTIVE OIL-BURNER.

Specification of Letters Patent.

Patented Nov. 5, 1907.

Application filed September 19, 1905; Serial No. 279,188-

To all whom it may concern:

Be it known that I, GEORGE E. Wrrr, a citizen of the United States,residing at San Francisco, in the county of San Francisco and State ofCalifornia, have invented certain new and useful Improvements inLocomotive Oil-Burners; and I do hereby declare the following to be afull, clear, and exact description of the same, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to improvements in oil burners, and moreparticularly to those used in locomotives, and it has for its objects toprovide a device of this class which shall possess superior advantagesin points of simplicity of construction, as well as inexpensiveness andgeneral efiiciency.

In my. invention 1 have made it possible to regulate the size of theflame without the necessity of delicate and readily destructiblemechanism.

In my present invention there are no adjustable parts liable to get outof order, as the burner proper is made of a single casting.

Other objects and advantages of the inventionwill appear in thefollowing specifications, and the novel features thereof will beparticularly pointed out in the appended claims.

In the accompanying drawings, in which similar letters of referencedesignate corresponding parts: Figure 1 is a longitudinal centralsection of the burner. Fig. 2 is a transverse section on the line mo ofFig. 1. Fig. 3 is an end view of the mouth of the burner.

Referring now to the above views, A represents the main body of theburner which is a hollow casting with the central web B which dividesthe interior into the longitudinal passages C and D, the former for thepassage of oil and the latter for steam. Leading to the rear of theupper passage C is the threaded boss E which is adapted to receive theoil pipe; while the passage D terminates in the threaded boss F whichreceives the steam pipe.

The forward end of the oil passage C is open; while that of the steampassage D is closed with the exception of a transverse horizontal slot(a). The end wall of the passage D, through which the slot (a) is cut,sets back slightly from the extremity of the main casting therebyforming a lip (b) which inclines downward toward the center of thecasting as shown in Fig. 3.

From the description so far gone into it will be readily seen that asthe oil reaches the outer extremity of the passage C it will flowdownward until it reaches the slot (11) when thesteam issuing from theslot will intermingle with the oil and produce the desired result. N

Now directly below\the lowest portion of the lip (b) flame is theresult.

is a hollow projection G into which is cut the slot (9). The smallpipe Hwhich is threaded into the pr0jec tion G is provided to carry steam tothe slot (9). Now it is manifest that when it is desired to reduce theflame the steam passing through the passage D is cut off and allowed toflow through the small pipe H. Of course the oil flowing into the lip(12) will overflow and finally reach the small slot (g) where thediminished flow of I steam is encountered and a correspondingly small Itwill be noticed by reference to Figs. 1 and 3 that the upper edges ofthe lip B dip slightly inward in order to prevent the oil from flowingfrom the lip until it reaches the lower portion thereof.

The rear leg J and central legs K are merely for the purpose of holdingthe small pipe H in place.

The construction and arrangement of the several parts of my burner beingthus made known, the operation and the many advantages of the same will,it is thought, be readily understood by those familiar with the use ofoil burners.

Havingthus fully described my invention, what I claim and desire tosecure by Letters Patent is:

1. In a device of the character described, a hollow cas- 7 ing having acentral web dividing its interior into parallel .7

upper and lower passages, said casing having means by which saidpassages may be respectively connected to an oil and steam supply, saidoil passage extending through the front end of the casing and said webterminating short of the front extremity of the casing, and saidcasing'having' a vertical wall connecting with the front end of the weband extending over and closing the front end of the underlying steampassage except for a slit in said wall, said casing having a lippositioned in front of and below said slit, to enable the oil emergingfrom the oil passage to flow downward over said wall and across saidslit into the range of action of the steam issuing from the latter.

2. In an oil burner the combination of a hollow casing having a webwhich divides its interior into upper and lower passages for oil andsteam respectively said Web 'terminating short of the front end of thecasing and conmental steam pipe entering said hollow projection and de-'livering steam thereto whereby oil overflowing the lip will flow downover the wall of the hollow projection and into the range of action ofthe steam delivered through the slit in said projection.

3. An oil burner provided with oil and steam passages having outletsarranged in parallel relation, the oil outlet being provided with agutter. of maximum depth at the center and having a rear dam wall, acentral bottom wall, side walls inclining downwardly from the sides ofthe outlet to the bottom wall, and barrier lips projecting up wardlyfrom the outer edges of the side walls in parallel lips projectingupwardly from said side walls and inclined 1O relation to said dam walland inclining downwardly from toward the deepest portion of the gutterand separated to the sides of the outlet to said bottom wall, the bottomform a shelf for the reduced flow of oil therethrough.
